Solution Overview
Problem
Drinking water in storage tanks is prone to temperature layer formation, leading to algae growth, bacterial loads, and uncontrolled chemical concentrations due to lack of liquid exchange, which conventional agitators fail to address effectively.
Innovation Solution
A submersible agitator device with a hyperboloid agitator body, radially angled supports, and an annular flow-guiding element that reduces vortex formation, enhancing agitation efficiency and energy efficiency by directing flow radially and avoiding circular or spiralled vortices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional agitator devices are used to circulate drinking water, then some agitation effect is achieved, but temperature layer formation persists and energy expenditure is high
Solution Approach 1:
The patent applies the counterweight principle by introducing a flow-guiding element that creates an opposing flow pattern to counteract vortex formation. The flow-guiding element directs water flow in a manner that opposes the natural rotational tendency of the agitator, thereby eliminating circular and spiralled vortices that consume energy without achieving effective agitation.
Solution Approach 2:
The patent converts the harmful effect of vortex formation into a beneficial flow pattern. By strategically positioning the flow-guiding element, the water flow that would otherwise create energy-wasting vortices is redirected to produce effective radial circulation. The flow-guiding element transforms potentially harmful rotational flow into beneficial agitation that prevents temperature layer formation.
2Productivity
If the agitator device creates strong circulation flow, then temperature layer formation is prevented, but circular or spiralled vortices form reducing efficiency
Solution Approach 1:
The patent converts the harmful effect of vortex formation into a beneficial flow pattern. By strategically positioning the flow-guiding element, the water flow that would otherwise create energy-wasting vortices is redirected to produce effective radial circulation. The flow-guiding element transforms potentially harmful rotational flow into beneficial agitation that prevents temperature layer formation.
Solution Approach 2:
The flow-guiding element acts as an intermediary between the agitator and the water flow. It mediates the interaction by directing and shaping the water flow in a controlled manner, preventing the formation of circular and spiralled vortices while maintaining effective radial circulation. This intermediary component ensures that energy is not lost to vortex formation but is instead utilized for productive agitation.
3Ease of manufacture
If the agitator device is designed with simple structure, then manufacturing is easier, but agitation efficiency may be insufficient
Solution Approach 1:
The patent applies segmentation by dividing the agitator device into distinct functional components: the agitator body, the flow-guiding element, and the support structure. This segmentation allows each component to be optimized independently for its specific function while maintaining overall structural simplicity. The flow-guiding element is designed as a separate, easily manufacturable component that can be attached to the agitator assembly.
Solution Approach 2:
The patent utilizes curvature in the design of the flow-guiding element and the support structure bend portions. These curved surfaces guide water flow smoothly without creating abrupt changes that would generate vortices. The curved geometry is both aesthetically pleasing and functionally effective, achieving high agitation efficiency while remaining simple to manufacture using standard forming processes.

Function Achieved in This Case
The device achieves improved agitation efficiency and reduced energy expenditure for circulating drinking water, effectively preventing temperature layer formation and associated issues.
Implementation Method 1
As thehyperboloid agitator body rotates, a flow directed to the upper side thereof is generated and is deflected in a radial direction towards the peripheral edge
Implementation Method 2
Due to the provision of the annular flow-guiding element, circular or spiralled vortices at the periphery of thehyperboloid agitator body are avoided
